This guy injects Heroin (I didn't even know you could smoke it by the way). That means he is injecting all kinds of rubbish along with his drug of choice. Brick dust, sand, talc. It is added (cut) with the Heroin by the dealers to increase the amount they can sell. This destroys your body and circulation. They can nead amputations and other lumps cut from their body. Not to mention the HIV risk from shared needles. Also because you have no idea how strong a particular dose is (it depends on how much rubbish it is cut with) they risk overdose every time. It is so addictive most women on the drug turn to prostitution to fund their habit. It funds some very shady nasty people. Do you want to fund the people who train Moslems to blow themselves up. Now if it were legalised most of these problems could be sorted. But do you really want an unproductive drug addicted society? Do you want your train driver/ambulance paramedic on a high? Prescribe it to addicts I say (on a treatment program) but leave it to that.
